Induced angular momentum
G. W. Parker
Abstract
The angular momentum induced in the bound motion of an electron by an external magnetic field B is evaluated classically and quantum mechanically. The quantum-mechanical model used is one in which the angular momentum is quenched when B=0 so that it is representative of a molecule rather than an atom. The current density and its associated magnetic moment are calculated and discussed. Two different methods are used to solve the first-order perturbation theory equation for the required eigenfunction.
